I am adding a few of the photos (From the auction) on here so we can see them after the auction ends if people are interested. The description that came with this auction was:

"Ernst Bohne Sons
Rudolstadt, Thuringia, Germany
1878-1920

Offered for auction is this awesome Victorian Era porcelain skull mug produced by Ernst Brohne Rudolstadt, Germany and most likely dates to the 1890's. This cool mug is the original from which all others copied. We've seen this early skull mug by Brohne but usually in a larger lidded stein version. This rare mug measures 3.75" tall by 5" long. The bottom is stamped with the B on Anchor mark."

I thought some of you might of liked to of seen this very early skull mug.

The Skull -- Mortality Unmasked
"The opposite of the mask is the skull. The face of the person is a fleshy skin worn between the two. People who deny the person as made in the image of God directly, and individually created and loved by Him, will seek either of these exits to being truly human -- the mask which covers the mortal man or the skull which is left after mortal man has departed..."
